Kale in My Teeth

Jenn Sherman is one of Peloton's first-ever instructors, a cycling icon who has been leading riders for over 13 years and recently turned her focus to what she calls the Back Nine Era — redefining strength, longevity, and midlife fitness for women. She and Rivki talk about why cardio alone stops being enough in midlife, what her Back Nine Era mindset really means for how women should be moving and fueling their bodies, and why she now spends five days a week lifting weights instead of riding. They also get into the reality of navigating menopause — the mood shifts, disrupted sleep, and bone density wake-up calls nobody warned her about — and why Jenn believes this chapter of life is less about declining and more about pivoting into the strongest version of yourself yet.

Joyce Chabbott is a content creator and mom of four who built her platform around life on the Upper East Side. In this episode, she and Rivki talk about the decision to intentionally share her life online and navigating criticism that she "glorifies motherhood" by not filming tantrums, why she teaches her kids about their privilege instead of hiding it from them, and the isolating experience of becoming a content creator when no one in your real life understands what you're doing. They also discuss setting boundaries with what her kids share about their friends, the fast-paced culture of raising kids in New York City, and how going viral by accident turned into an empowering career she built while still being fully present for her family.

Kelsey Rose is a certified personal trainer and founder of the Shaep app who transformed her approach from overworking her body to finding sustainable balance. In this episode, she and Rivki talk about her journey from teaching education to building a fitness business during the pandemic, why she combines strength training with Pilates instead of choosing one or the other, and her simplified approach to nutrition that focuses on protein, carbs, and vegetables without overthinking it. They also discuss cycle syncing workouts to your menstrual phases, why walking is the most underrated wellness habit, and how scaling back your intensity can actually get you better results when you stop forcing your body to do things it doesn't enjoy.

Vita Sidorkina is a former model turned wellness entrepreneur who built her career walking for Victoria's Secret before stepping away to become a mother. In this episode, she and Rivki talk about growing up in Russia with ambitious, loving parents who taught her resilience, losing her identity when modeling ended and she became a wife and mom simultaneously, and navigating postpartum depression while rebuilding from scratch. They also discuss why discipline beats motivation every time, the problem with fitness trends (from vegan to protein obsession), and how she created The Core—a wellness app built on personal struggles, not textbook theories—that launches with workouts, nutrition, and mindset coaching all in one place.

Stephanie Gottlieb is the woman behind some of the most recognizable fine jewelry in the world, building a luxury brand that bridges the gap between fine jewelry and everyday fashion. In this episode, she and Rivki talk about taking the intimidation out of fine jewelry purchases, the challenge of relinquishing creative control while building a team, and navigating the tension between being the face of your brand and wanting it to exist beyond you. They also discuss why staying true to your brand DNA is the only sustainable business strategy, the evolution from rainbow maximalist to letting jewelry take centre stage, and how the right people around you can unlock growth you didn't know was possible.
